Kozlovka is a village in the Kstovo district, known as an archaeological monument due to the Kozlovskoye settlement, dated to the 13th-18th centuries. According to information provided by Yulia Sukhonina, the estate of the Kozlovs has partially survived in Kozlovka. Here you can see the remnants of an old house with tall windows, a pond, a park with linden alleys, ancient oaks, and Baranov spring. In 2000, a chapel was built in the village on the site where the previous structure was destroyed in 1940.
